The base is midwinter quality right now, and that is midwinter in a good year. This season has been insane. We rent a ski lease from November 20 to May 20, so we come up at least 2 weekends a month. I made 12 trips this year, two 7-8 day trips and 10 2-3 day trips, and it was one of the best winters I have had since I left Tahoe and the ski bum life. If we still had our ski lease I might do another trip, but to be honest I am pretty burnt on the drive. 6 hours each way is pretty tough, during the winter I am used to it, but starting in May I get sick of it. I don't see doing another trip because I don't want to pay for lodging and the surf has been good down here, but I would encourage anyone who wants to make some turns to go to Mammoth.
Go to mammothsnowman.com to see some pics of the mountain right now. The coverage up high is seriously midwinter in a big year level.
